5 conductor cable for tube mic (cat5? midi?)

[buschfsu]

looking for diy-esque alternatives for 5 conductor cables with B+ at 90v.
my options are cat5e or midi cables. anyone try this or should i buck up and buy the real thing?


thanks

do midi cables have 5 wires? they only use 3 pins and most of the cables iveseen only have those 3 pins wired. i would also doubt that the cat5 could handle the high voltage for long. there are several places toget multiconnection tube mic cable.

$1.60 a foot. cant beat that.

It depends on the brand. MY buddy had a johnson guitar amp that had a midi cable that would go to the foot controller. Anyway when using monster cable it never worked because only 3 of the pins wired and I guessed that they were sending voltages to power the unit on the other pins. Put in a cheap hosa cable and it worked prefect. So hosa wires all 5 pins.

That's not a MIDI cable then. It's a pin-to-pin DIN cable. Din cables work for MIDI, MIDI cables don't always work for pin-to-pin DIN uses.

The MIDI spec only used two pins as I understood it...

Part of the problem is that people call 5-pin-DIN connectors MIDI connectors...

I've seen Hosa cables wired for 3 pin, 4 pin and 5 pin. I don't know why we have so many of these crappy cables around here, but all the Hosa cables have tags indicating how many pins they are. To really throw things off, the 4 pinners aren't even pinned the same between them...

As ar as tube mic cables, Gotham makes good stuff. I think it's GAC-5 or something like that.

Hello,

Gotham makes GAC-7 for tube mics.
Available at RS, in Europe.
For tube mics I have used with success some Mogami cable originally designed for RS422 links ( 2 pair + drain/shield ) and 4 wires

The MIDI spec is only 3 pins, but the other two pins on the connector are sometimes used to send power to controllers, as in foot controllers etc. As for tube mic cable, you need something that has excellent shielding and a good twisted pair for the mic signal. Try the Mogami 3172. It is specifically designed for tube microphones. It has a double shield, 26ga twisted pair for mic signal, 2 wires for bias, and two wirees for heater. The cost is about $1.40 per foot. As for CAT5, I wouldn't recommend it as it has no shield.

Cheers,
